1. CTBN jẹ ẹya o tayọ ni irọrun modifier fun thermosetting resins bi iposii, phenolic, unsaturated poliesita ati photosensitive resini. O le mu ilọsiwaju brittleness ati resistance dojuijako ti ọja ikẹhin.
2. Awọn alemora ti fadaka ti a ṣe lati inu resini epoxy ti a ṣe atunṣe nipasẹ CTBN (akoonu acrylonitrile jẹ 25%), ni lile lile, irọrun ati aarẹ resistance. O le ṣee lo lati sopọ mọ awọn paati ti ọkọ ofurufu, bakanna bi gilasi Organic ati igbanu terylene. Yi alemora tun le ṣee lo bi seeping alemora ti awọn orisirisi awọn ohun elo asọ bi gilasi okun, terylene ati erogba okun.
3. Adhesive ti a ṣe lati CTBN ati epoxy resini le ṣe iwosan ni iwọn otutu deede, o le ṣee lo lati ṣe asopọ awọn ohun elo alumini, yoo de iwọn ifarapa ti o ga julọ lẹhin awọn wakati 72. Peeli-kikanju jẹ 0.55MPa, ati kikankikan gige jẹ 26.7MPa. Awọn ohun elo elekitiriki elekitiriki ti a ṣe nipasẹ iposii ti CTBN ti a yipada, eyiti o mu ki resistance wo inu, kii yoo ni kiraki lẹhin awọn akoko 200 atunlo ni iwọn otutu laarin -55.0℃ si 150℃.
4. Awọn CTBN le ṣee lo bi adhesive ni lilọ ati gige kẹkẹ, o ni awọn anfani ti o kere ju alemora ṣugbọn diẹ sii abrasion resistance, bakannaa iṣẹ ti pólándì ti o dara, omi gbona resistance.
